Postharvest Behaviour of Cut Tuberose Spikes as Affected by Chemicals

The experiments were conducted to study the effect of various chemicals, viz., boric acid, AL₂ (SO₄)₃, CaCL₂, AgNO₃, CoCl₂ and citric acid on postharvest life and quality of cut tuberose flowers. Among different concentrations used, boric acid (250 ppm), Al₂ (SO₄)₃ (50 ppm), CaCL₂ (1000 ppm), AgNO₃ (50 ppm), CoCl₂ (25 ppm) and citric acid (400 ppm) were found beneficial for improving opening of florets, flower diameter, useful life and longevity of spikes.
